Containment Water Wastewater Chemical Fuel Nuclear Tunnels and Concrete Pipes Manholes
5
Erosion Alkali Silica Reaction Sulfate Attack Reinforcing Corrosion Shrinkage and Cracks Chemical
7
Limited Abrasion Resistance Limited ASR Mitigation Limited in Sulfate Resistance Limited Chemical Resistance Very Porous Shrinkage Cracks Coatings – 30 plus days to apply
8
ASTM C-1600 Rapid Hardening Hydraulic Cements Calcium Sulfoaluminate Cement Specific Blended Cements Potential Portland Cement with Specific Supplementary Cementitious Materials (SCMs) Fly Ash Slag Metakailan Calcium Aluminate ASTM C-845 Type K Shrinkage Compensating
10
Can be Most Any Natural or Blended Rapid Strength Hydraulic Cement System Intention is to Create a Cement Solution That All End User Has to do is Add Water and Aggregates Admixture Friendly Bulk or Packaged Products
11
Performance Specification Clearly Defines the Cement by Speed of Strength Development Tests Include Strength Development Set Shrinkage Expansion Sulfate Resistance Heat Hydration Alkali Silica Reactivity
13
Very Rapid Hardening – 3000 psi 1 to 3 hours Very Low Shrinkage – Volume Stability Limited Expansion No Carbonization No C 3 A in Chemistry – Sulfate Resistant Very Low Alkali – Addresses ASR Issues Low Heat of Hydration Low Porosity High Abrasion Resistance Coatings Can Be Applied Within Hours
14
User Friendly – Requires.45 to.50 water Cement Ratio – 4” slump without WRs Most Traditional Admixtures Work Well with CSA – Including Corrosion Inhibitors Reduce Permeability Using New Gen Polymers or Mod A Latex Can Be Used With Cathodic Devices and Impressed Systems LEED Points
15
Portland and SCMs Limited Reduction in ASR and Sulfate Slow Strength Development without Adds Moderate to High Shrinkage Mineral Based Cements Specific End Results Differ with Each Product
17
Portland Cement Based Products w/ Adds Dominate Market Portland Blends CSA Cement Mineral Admixtures Mineral Based Chemical – i.e. Mag Phosphate
18
Each Has Specific Characteristics Each Has a Specific Application Each Has Specific Mixing Instruction Each Have Differing Content READ DATA SHEET BEFORE SPECIFYING and USE
20
Many Repairs in Containment Require Large Quantity of Grout as Some Type of Fill Type K Grout Can be Delivered to Job Site in Conventional Ready Mix Trucks at 50% the Cost of Bagged Non-Shrink Grouts (material cost)
21
Utilize ICRI Guidelines to Determine the Cause and Appropriate Repair Use ICRI Surface Prep Profile Guidelines Select Cement Based Concrete That Meets the Owners Requirements
